Yes, it was hot-swapping S2 pump batteries. Ditching the dead weight maximizes performance.

 

The payloads were for two smallsat constellations,

 

1x Planet Lab Dove Pioneer (Earth observation)

 

2x Spire Global Lemur-2 (ship tracking, meteorology)

Rocket Lab flew a Fregat-style kick stage on Electron named "Curie". Looks like there's plenty of room for extra or larger tanks.

 

Powered by a green monopropllant, which may be the shear-thinning monopropellant they developed under a 2011 DARPA contract.

 

Way to go, guys!

SOUTH SAN FRANCISCO, Calif.  The successful launch of Rocket Labs Electron rocket Jan. 20 also tested a kick stage designed to circularize the orbits of its satellite payloads.

The company said Jan. 23 that the Electron carried a kick stage for the two Lemur-2 cubesats it launched for Spire. The kick stage separated from the Electrons upper stage and, after a 40-minute coast phase, fired an engine called Curie to circularize its orbits before releasing the cubesats.

The Electrons upper stage placed the kick stage, as well as a Dove cubesat from Planet, into orbits of approximately 300 by 500 kilometers. Data from the U.S. Strategic Commands Space Track website shows that three of the objects, not identified but believed to be the two Lemur-2 cubesats and the kick stage, are in orbits with perigees of 490 to 500 kilometers and apogees of 530 to 535 kilometers, far more circular than the other objects tracked from the launch.

Beck said the stage could perform a number of applications to change orbits of its payloads, but didn't disclose technical specifications like the stages total delta-v. The stage could also lower its orbit after satellite deployments to minimize its time in orbit before reentry. "We can be much more conscious and deliberate about ensuring we dont leave stuff behind," he said.

My bet is they'll announce two: VAFB and Wallops. VAFB (for the Polar Azimuth flights there's no better place to launch from) and Wallops (because that place needs more activity and the Cape is pretty full up right now with SpaceX, NASA, DOD & ULA).

 

Barring Wallops, the Cape could always break in the new Light Pads with Rocket Lab. It'd be perfect, really.

They can do polar and SSO from NZ, which will remain open for business.

 

It was my understanding their lead  candidate was at KSC LC-48; one of  two new small launcher pads situated between LC-39A and LC-41.

 

Good for LEO and SSO, and polar capable if they install an autonomous flight termination system like Falcon 9/Heavy - which IS being commercialized.

Ow, that tracking station was fixed on the same day!

 

It was the same motor controller issue that bit them back in April again that stalled the launch...

Here you go world. An exclusive look inside @RocketLab's secret brand new factory or perhaps modern art museum. Rocket Lab just dropped a NUKE on the small sat industry. This place is STUNNING!!!

Exclusive interview and image op....this is quite the factory and the control room is a knockout.

No offense but uhm... "It's business time" still isn't launched! Lot's of racket, very few launches so far. Nice that they got this huge ass factory that poops out rockets, but it's time to start launching these darn things already!

Same could be said for Vector and Blue origin.

 

Blue Origin will be Blue Origin and can afford to be cautious.

Vector....will talk themselves into the fog...

 

Rocket Lab reminds me of a mini-me SpaceX. They are agile, embrace technology and have a good manifest but are being tight lipped about the motor controller and software. I have a hunch that they have redesigned it and are into testing to make this issue go away, for good...as SpaceX would do.  When they get going in the new year, they will be tough to catch.....patience is the key as they really are only competing with themselves in their mind, at the moment.
